Matlab Help: How to load this into an array?

[uCsDNerd]

Hi All,
I have a large text file containing network packet sniffer data (example below). I'd like to load this file into matlab as an array so that I may filter the file for lines that contain a certain IP address and packet ID number.

#### Original File Data (altered IPs) ####
0 1056650630.099362 xxx.xx.220.40 xxx.xx.129.134 6 22 3221 53489 1500 0.113983

The problem that I am having is that when loading the file into matlab using the commands:

A = load('network.log');
B = num2str(B);

0 1056650593.8984 xxx.xx xxx.xx 6 22 214 5546 88 0.163508


Not only does it only round off my timestamps (column 2), it also truncates my IP addresses!!
Can someone please tell me how can I get around this?

Thank you!

I don't know if this will work, but you could try entering 'format long' (without the quotes) before you load the data in from the file.

It's possible that it's only displaying in way you don't expect, but it still has the info in place. I suppose you could always use fscanf or some cousin of it (try "help fscanf").
